[Machine] The Messenger of Allah, ﷺ , mentioned in a narration about the prayer of the Prophet, ﷺ , that she said:

"So he used to say the greeting between every two units of prayer, as mentioned in the book of Muslim from the narration of Husayn ibn Dakhwan al-Mu'alim, except that he said, and he used to say the greeting in every two units of prayer."  

كَانَ رَسُولُ اللهِ ﷺ فَذَكَرَ الْحَدِيثَ فِي صَلَاةِ النَّبِيِّ ﷺ قَالَتْ فَكَانَ يَقُولُ بَيْنَ كُلِّ رَكْعَتَيْنِ تَحِيَّةً مُخَرَّجٌ فِي كِتَابِ مُسْلِمٍ مِنْ حَدِيثِ حُسَيْنِ بْنِ ذَكْوَانَ الْمُعَلِّمِ إِلَّا أَنَّهُ قَالَ وَكَانَ يَقُولُ فِي كُلِّ رَكْعَتَيْنِ التَّحِيَّةَ  

When you get up to pray, say the takbir, exalting Allah; then recite the Qur’an as much as it is convenient for you. The version adds: When you sit in the middle of the prayer, do it completely(so that you are at rest) and spread your left thigh; then recite the tashahhud. Then if you get up (again), do in a similar way until you finish your prayer. (Using translation from Abū Dāʾūd 860)   

عَنِ النَّبِيِّ ﷺ فَذَكَرَ حَدِيثَ الصَّلَاةِ وَقَالَ فِيهِ فَإِذَا أَنْتَ قُمْتَ فِي صَلَاتِكَ فَكَبِّرِ اللهَ ثُمَّ اقْرَأْ مَا تَيَسَّرَ عَلَيْكَ مِنَ الْقُرْآنِ وَقَالَ فِيهِ فَإِذَا جَلَسْتَ فِي وَسَطِ الصَّلَاةِ فَاطْمَئِنَّ وَافْتَرِشْ فَخِذَكَ الْيُسْرَى ثُمَّ تَشَهَّدْ ثُمَّ إِذَا قُمْتَ فَمِثْلُ ذَلِكَ حَتَّى تَفْرُغَ مِنْ صَلَاتِكَ
